Description

Technical Field

[0001] The present invention relates to the technical field of cooling treatment, in particular to a quenching device of a thermal simulation testing machine. Background Art

[0002] Thermal simulation testing machine is one of the most widely used equipment in the field of high-temperature performance testing of metal materials and simulation research of thermal processing technology in production sites.

[0003] High-temperature properties of metal materials include high-temperature tensile properties, high-temperature strength, high-temperature elongation, and high-temperature reduction of area. Simulation of hot processing processes at production sites includes rolling, forging, extrusion, and heat treatment. During heat treatment, steel parts must be quenched to improve their performance or preserve their high-temperature microstructure. For example, the Gleeble thermal simulation tester produced by DSI (USA) includes a built-in quenching device. However, its disadvantage is that water spray quenching creates a large splash during quenching, filling the entire sample chamber with water after quenching. Cleaning the chamber is extremely time-consuming and difficult to do thoroughly. A wet sample chamber cannot remain dry, hindering subsequent vacuum extraction and potentially damaging the vacuum equipment. During jet quenching, samples can often fail to fully quench after being compressed to a very flat state. Some studies have attempted to remove the sample from the compression shafts and place it in prepared water after the experiment, but the results have been unsatisfactory. Since the two processes from the end of the experiment to the stopping of the equipment, and then the retreat of the hydraulic axis until the sample is taken out, take at least 5-6 seconds. After 5-6 seconds, the sample temperature has dropped by about 300 ° C, making it difficult to achieve the purpose of high-temperature quenching. In addition, when the sample chamber is opened immediately after the experiment to take samples, the exhaust gas in the sample chamber is more harmful to the human body. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] It should be noted that, in the description of the present invention, the terms "up", "down", "top", "bottom", "one side", "the other side", "left", "right", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0022] See attached Figure 1 and 2 The detailed structure of an embodiment of a quenching device for a thermal simulation test machine proposed in the present invention is shown. The device comprises a metal box 1, a box cover 6, a large hollow sphere 9, a small solid sphere 10, a robotic arm 11, a robotic hand 12, a fixed base 15, a base 16, and an elastic cable 17.

[0023] Among them, a first screw hole 4 is opened in the middle of the rear side of the metal box 1, and a second screw hole 14 corresponding to the first screw hole 4 is set in the middle of the front side of the fixed base 15, and the metal box 1 and the fixed base 15 are fixed by screws; a slide groove 2 is set on the top of the metal box 1; the box cover 6 is correspondingly slidably connected to the inside of the slide groove 2; the box cover 6 has a sealing effect on the metal box 1, so that the water in the metal box 1 will not splash out of the metal box 1 when the vacuum unit evacuates the sample chamber, that is, the water-containing metal box 1 is placed in the sample chamber as a whole without affecting the vacuuming of the sample chamber; a drain port 7 is set at one end of the bottom of the front side wall of the metal box 1; the base 16 is fixed integrally on the fixed base 15. The upper end surface of the fixed base 15; the hollow large sphere 9 is embedded in the middle of the base 16 and the upper end is open; the lower end of the robotic arm 11 is in contact with the inside of the hollow large sphere 9 through a coaxially fixed solid small sphere 10; the front and rear sides of the upper part of the hollow large sphere 9 are respectively provided with slots corresponding to the diameter of the robotic arm 11; the robotic arm 12 is correspondingly fixed to the middle part of the upper end surface of the robotic arm; one end of the elastic cable 17 is connected to the upper rear part of the robotic arm 11, and the other end is connected to the middle part of the rear side of the fixed base 15 through a switch. When the robotic arm 11 is not working, it is placed at an angle of 45° through the elastic cable 17; a robotic arm activity sensor 13 is provided on one side of the rear end surface of the fixed base 15. When the elastic cable 17 is induced, the switch connected to the fixed base 15 is turned on, and the robotic arm 11 falls along the front opening of the hollow sphere 9 and hits the sample. The robotic arm 11 and the manipulator 12 use their gravity to knock the sample down, and the sample falls into the water in the metal box 1, achieving the purpose of quenching. After the quenching process is completed, the robotic arm is controlled by the remote control to rise, and the metal box is closed at the same time. The metal box is in a sealed state, and the sample chamber begins to be vacuumed and the exhaust gas is discharged, completing a complete quenching experiment.

[0024] In this embodiment, a cover opening sensor 5 is provided at the left end of the upper surface of the box cover 6. When the cover opening sensor 5 senses that the hydraulic shaft retreats, the box cover 6 is controlled to automatically and quickly slide to the left.

[0025] Rubber strips 3 are provided on the right end face of the lid 6 and at corresponding positions on the top of the right inner wall of the metal box 1. The length of the rubber strips 3 corresponds to the length of the lid 6 and the metal box 1. The rubber strips 3 ensure the tightness of the metal box 1 after quenching. When the lid 6 is closed, the thermocouple wire connecting the sample and the external temperature measurement channel of the metal box 1 becomes stuck between the lid 6 and the metal box 1, affecting the tightness of the metal box 1. Therefore, rubber strips 3 are installed on the right side of the lid 6 and the right side of the metal box 1. Even if the thermocouple wire becomes stuck between the rubber strips 3, the elasticity of the rubber strips 3 allows the 0.2mm diameter thermocouple wire to remain firmly embedded between the rubber strips 3, ensuring that the thermocouple wire does not affect the tightness of the metal box 1. After quenching, the sample chamber can be evacuated again to extract toxic waste gases from the sample chamber and prevent them from causing harm to human health.

[0026] The four corners of the bottom surface of the metal box 1 are respectively provided with rubber feet 8 to prevent wear at the contact point between the metal box 1 and the sample chamber.

[0027] In this embodiment, the metal box 1 is made of stainless steel and contains water; the fixed base 15 is a hollow stainless steel shell with a rectangular structure; and the main body of the robotic arm 11 is a solid stainless steel cylinder.

[0028] The purpose of the present invention is, firstly, that when the entire device of the invention is placed in the sample chamber of the Gleeble thermal simulation test machine, the sample chamber can be normally vacuumed before and after the experiment; secondly, that the sample can be quenched at the end of the experiment. The specific working principle is: after the experimental sample is loaded before the experiment, the entire device of the present invention is placed in a suitable position in the sample chamber. At this time, the metal box is filled with a certain amount of water and is in a sealed state. At the moment the experiment ends, when the sensor on the metal box cover and the sensor of the robotic arm are sensed, the metal box cover slides to one side, and at the same time the robotic arm tilts and hits the sample, and the sample falls into the water in the metal box to achieve quenching. After the quenching is completed, the lid of the metal box is closed again by the remote control, and the experimental sample and the water in the metal box are sealed in the metal box. The sample chamber is vacuumed again, and the exhaust gas in the sample chamber is extracted to complete the entire quenching operation process.

[0029] Matters not covered in the present invention are all known technologies.

[0030] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
